SASH-FASTENER.

SPECIFICATION forming part of Letters Patent No. 238,627, dated March 8,1881.

Application filed August 5, 1880.

T 0 all whom it may concern:

Beit known that I,WILLIAM HENRY WOLF- RATH, of the city and county ofNew York, and State of New York, have invented a new and usefulImprovement in Railroad-Oar-Sash Manipulators, of which the following isa complete and exact description, reference being bad to theaccompanying drawings, forming part thereof.

This invention relates to sash fasteners which are operated by a knob,spring, and sliding rod; and it consists in the peculiar constructionand combination of parts, hereinafter set forth.

Figure 1 represents a side view of a portion of a sash with my fasteningdevices attached, also a part of the frame with which the fastening boltengages. Fig. 2 represents the fastener in perspective, some of theparts being slightly modified.

The fastening-boltA passes through the side of the sash near its lowerend, and is provided with a spring, I), that forces it outward. From therear end of said bolt a rod, (1, extends to the end of acrank-arm, 0,carried by the shank of a knob, E. This crank-arm is also provided witha pin, a, which is arranged to engage the (MOdcL) lower end of a lever,0, that is pivoted at its middle, and connected at its upper end to therear end of a rod, d. The forward end of said rod is attached to therear end of bolt A. When said knob is rotated in one direction the draftof arm 0 on rod (1 withdraws the bolt. When said knob is rotated in theother direction the action of pin 0 on lever 0 effects the same resultthrough rod d.

The fastening-bolt may have either a barshaped end, as shown in Fig. 1,or a recessed head, as shown in Fig. 2. In the former case it engageswith recesses in the frame, and in the other case with a rack attachedthereto.

What I claim as my invention, and desire to secure by Letters Patent,is-

Ina sash-fastener, the combination of the fastening-bolt A, spring I),and rods 61 d with the pivoted crescent-shaped lever c, the crankarm a,stud or pin 0, and knob E, said parts being connected and operatedsubstantially as set forth.
